Woman reports rape in downtown Ann Arbor parking structure elevator

The victim, a 26-year-old Ypsilanti woman, did not go to the hospital after the rape. She reported the attack after seeing media coverage of the other attacks, Bush said.

"We're obviously very concerned and we're working very hard to try to get the suspects identified," Bush said.

The attacker was described as white, 26 years of age, 5 feet, 6 inches to 5 feet, 7 inches tall, with short, dark and straight hair, police said.

In all 5 recent attacks, the description of the attacker includes the same height and similar additional features.

Police have said they're considering a serial rapist scenario, but also said on Thursday that no evidence supports that.

Police said on Thursday that they had a total of 4 complaints since last Friday involving women walking alone being assaulted by a man. In one case, a woman was raped on South State Street.

The parking structure has entrances on both East Liberty and East Washington, west of South State. It formerly was known as Tally Hall.

A representative of Republic Parking, the private company that's contracted to operate the downtown parking system, said she hadn't heard about the assault but couldn't comment further. DDA Executive Director Susan Pollay could not be reached for comment.

Meanwhile, the University of Michigan is increasing patrols near Central Campus, spokeswoman Diane Brown said in an email.

"We have increased police patrols of and nearby Central Campus especially during late night and early morning hours," she said. "This is an effort to provide more visibility and therefore a deterrent as well as try to generate more investigation leads."

U-M also has issued crime alerts about the off-campus attacks because of their proximity to campus., and also is offering safety tips to students.
